The Wacker Neuson is a genuine OEM Valve Kit designed for the RD27-100 and RD27-120 series hydrostatic vibratory tandem rollers, including standard and traction control configurations. As a factory-sourced component, this kit is manufactured to the exact specifications required by the RD27 platform, ensuring proper hydraulic function and a direct, hassle-free installation. Compatibility spans multiple serial number ranges across both the RD27-100 and RD27-120 machine families, making part number the correct choice for a wide range of RD27 units in the field. Keep this kit on hand as a planned service item to maintain peak hydraulic performance on your roller.
Key Features
- OEM-Spec Valve Components — Each component in this kit is manufactured to Wacker Neuson's exact tolerances, ensuring correct pressure ratings and sealing performance within the hydraulic circuit.
- Direct Drop-In Installation — Engineered specifically for the RD27 hydraulic system, the kit aligns with existing valve ports and mounting interfaces for a straightforward swap.
- Broad RD27 Fitment Coverage — Confirmed for RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control variants, covering a wide range of production serial numbers.
- Sustained Hydraulic Drive Performance — A correctly functioning valve assembly maintains smooth, responsive hydrostatic drive and vibration control; a worn or leaking valve can cause sluggish travel, erratic drum vibration, or loss of traction control function.
- Hydraulic System Integrity — Proper valve operation is essential to safe and predictable machine control on grade; using a correctly rated OEM kit helps prevent unintended pressure fluctuations in the drive circuit.
The valve kit is a service assembly for the hydraulic circuit of the RD27 tandem roller, providing the sealing elements, valve components, or both needed to restore proper fluid control within the system. On a hydrostatic vibratory roller, the hydraulic valves regulate flow and pressure to the drive motors and vibration system, directly affecting travel speed, drum compaction force, and — on traction control models — automatic wheel-slip correction. When valves wear, leak, or fail to seat correctly, operators may notice loss of drive response, inconsistent vibration output, or hydraulic fluid loss, all of which compromise compaction quality and machine control.
